... Philips Semiconductors IEC 60958 audio DAC 8 FUNCTIONAL DESCRIPTION The UDA1350ATS is a low cost audio IEC 60958 decoder with an on-board DAC. The minimum audio input sampling frequency conforming to the IEC60958 standard is 28.0 kHz and the maximum audio sampling frequency is 54.0 kHz. 8.1 ...

... Mbits 48.0 kHz, resulting in a data rate of 3.072 Mbits/s. s The UDA1350ATS supports timing level I, II and III as specified by the IEC 60958 standard. 8.4.2 The audio feature processor automatically provides de-emphasis for the IEC 60958 data stream in the static pin control mode and default mute at start-up in the L3 control mode ...

Page 10

... TEST3 0 2001 Mar 27 8.5 Control The UDA1350ATS can be controlled by means of static pins or via the L3 interface. For optimum use of the features of the UDA1350ATS the L3 control mode is recommended since only basic functions are available in the static pin control mode. It should be noted that the static pin control mode and L3 control mode are mutual exclusive ...

Page 11

... L3 CONTROL MODE The L3 control mode allows maximum flexibility in controlling the UDA1350ATS. It should be noted that in the L3 control mode several base-line functions are still controlled by pins on the device and that on start-up in the L3 control mode the output is explicitly muted by bit MT via the L3 interface. ...

... I NITIALISATION STRING For proper and reliable operation it is needed that the UDA1350ATS is initialized in the L3 control mode. This is needed to have the PLL start up after powering up of the device under all conditions. The initialisation string is given in Table 8. Table 8 L3 init string and set defaults after power-up. ...
